Clearing up gauge face.

The previous owner of our boat put some nice new gauges in the instrument panel. He replaced the speedo, tach and fuel gauge. Unfortunately they are white and modern and don't at all match the black medallion gauges the boat came with. He also decided to cut a new hole for the new tach and left the old tach on board. I've found a matching NOS speedo on ebay for 30 bucks. I've got a fuel gauge that is close to original and I'll be on the lookout for a replacement. That leaves the old cloudy tach. I seems to clear up when I wipe the plastic lens on it. Any recommendations on a something that could clear up the gauge??

In the past on other plastic parts I had some luck with Meguire's products but I see on their web site that plastic polish is different that the one I used years ago.I have been luckey with ebay when I was looking for gauges. What style are you looking for? Post a picture.

if this helps, and yes it is a proven method, but if you ever notice the new plastic headlights on cars? many fog and you can barely see the light coming out and alot of miracle products came out for this reason, I simply will wetsand in graduations depending on the foginess, and end with 2000 grit, and then buff with coumpound, works well and lasts

I have no experience with marine gauges, however, I have taken apart about a dozen vintage motorcycle gauges to repair/replace the faces with great success. They are usually constructed of a two piece housing, like two cups placed rim to rim, and there is a metal trim ring that is crimped over the two pieces holding them together. You can use a small flathead screwdriver to slowly pry up the crimp on the bottom of the gauge, and if you're careful you can seperate the two halves without damaging anything. After you're done, put the gauges back together and re-crimp the ring with a pair of small vise grips with the jaws wrapped in electrical tape so they dont scratch.

To repair faces, you can have a sign/print shop make you a vinyl sticker to place on the gauge faceplate. This is done all the time in the motorcycle world to restore faded faces.

I'll look and see if I can find some pictures of the process when I get home tonight.

regular compound, dont fall for the 2 ounces for 10 bucks

This may be old news...Summit sent a brochure with my last order on what looked like a new line of pseudo nos gauges. Wrong term? They looked nice.
